Well, impossible to prove of course but it reminds me of Ingvar Kamprad (the man behind IKEA) who used to drive an old Volvo when in Sweden to appear as a "man of the people".
In fact he had his main residence in Switzerland and was filthy rich which is a bit of a hard swallow especially in Sweden, a country still very much affected by the "Law of Jante".

A reporter that was doing a documentary about his wealth asked him once directly when stepping out of his old Volvo and Kamprad kinda lost it; it was a big kerfuffle at the time on the telly.
For those paying attention it was really revealing about the true nature of the man (let me add he was a young Nazi back in the day).
Most people came to his defense like the red-blooded capitalist gentleman commenting above about Buffet being a 100% American.
The older generation still swallow the farce hook, line and sinker. For the rest of us it's pretty clear it was a well thought-out facade to placate the plebeians to sell more cheap furniture.
> he was a young Nazi back in the day
He remained a Nazi member well into the 1950s, which I find truly bizzare.
